此外,不建议大家在竞赛中使用vector,这些库函数可能会拖慢运行速度,在竞赛中最好先计算好可能需要的数组大小,再按照方法1进行定义 十六、declaration of 'xxx' as multidimensional array must have bounds for all dimensions except the first 声明“xxx”为多维数组必须对除第一个维度外的所有维度都有边界 这是在...

template<typenameT>classVector{ … }; 使用这个Vector模板就可以产生很多的class(类),Vector <int> 、Vector <char> 、Vector < Vector <int> > 、Vector <Shape*> ……。 模板类的重点是类。表示的是由一个模板生成而来的类。 例子: 上面的Vector <int> 、Vector <char> 、……全是模板类。 这两个...
